During an exchange of emails Tuesday, the World Boxing Council informed Maxboxing that the winner of the April 20th unification bout between WBC junior middleweight champion Saul Alvarez and WBA junior middleweight champion Austin Trout will have to vacate one of the titles on the line after the bout.

Recently, the WBC has been strict in not allowing unifications with other sanctioning bodies. It was insisted by the Mexico-based organization that WBA super middleweight champion Andre Ward vacate his WBC title after beating Chad Dawson. BoxingScene’s Miguel Rivera also reported that WBC junior welterweight champion Danny Garcia will have to make his decision following his bout with Zab Judah on April 27. The same rules will go into effect for the junior middleweight unification.

“The WBC rules stipulate that the winner of fights between champions of different organizations has 10 days after the fight to decide which belt to keep,” said Vice President Mauricio Sulaiman in an email. “Each organization has different rules and pre-established commitments and obligations in their divisions.”

The comments back up the WBC’s train of thought since President Jose Sulaiman’s comments in June 2012, when during a press conference in Mexico, Sulaiman said the unifications would cause his organization to lose “authority and exclusivity.”

“The WBC has absolutely nothing against the IBF, WBA or WBO,” said Sulaiman in an email. “The WBC loses its position, authority and would become only observers at boxing matches more as a guest than a sanctioning body.

“By the splitting of authorities and responsibilities with the local boxing commissions, whose mandatory defense is the champion first to comply with? Whose rules and positions shall they respect?” Sulaiman asked. “The WBC does not need that. We are structured by 164 national commissions and 10 confederation affiliates that many safety and benevolent actions work for.”

Sulaiman also expressed he is confident that Saul Alvarez would keep the WBC belt if he were to win the fight.

“Alvarez will not be stripped of his title because he is one of the most loyal champions and he has already expressed his interest is only the WBC,” Sulaiman said.
